+# Versioning
+BitOps Docker images are packaged and hosted on [Docker Hub](https://hub.docker.com/r/bitovi/bitops).
+Here is how these images are named, versioned and tagged.
+
+* An image with a version tag containing a [semver](https://semver.org) (e.g. `2.0.0`) is immutable and refers to the [stable release](https://github.com/bitovi/bitops/releases).
+* A version tag equal to `latest` is always mutable and points to the latest [stable release](https://github.com/bitovi/bitops/releases).
+* A version tag containing `dev` is always mutable and refers to the current development state in the [`main`](https://github.com/bitovi/bitops/tree/main) repository branch.
+* A version tag containing `omnibus` points to the default image that includes recommended devops tools.
+* A version tag containing `base` refers to minimal image with no other tools. You can build a [custom BitOps image](plugins.md) from it.
+
+## Official Images
+To clear up any potential confusion regarding the versioning of the [`bitovi/bitops`](https://hub.docker.com/r/bitovi/bitops) image, we use the following table.
+
+| Image Name | PreInstalled Tools| Docker image name | Supported Cloud provider | Additional stable image tags | Development image tags (`main` branch) |
+|-|-|-|-|-|-|
+| omnibus | Terraform <br/> Cloudformation <br/> Ansible <br/> Helm <br/> Kubectl <br/> AWS CLI| `bitovi/bitops:2.0.0-omnibus` | AWS | `latest` <br/> `2.0.0` | `dev` |
+| | | | | | | | 
+| aws-terraform | Terraform <br/> AWS CLI | `bitovi/bitops:2.0.0-aws-terraform` | AWS | | |
+| aws-ansible   | Ansible <br/> AWS CLI | `bitovi/bitops:2.0.0-aws-ansible` | AWS | | | 
+| aws-helm      | Helm <br/> Terraform <br/> AWS CLI | `bitovi/bitops:2.0.0-aws-helm` | AWS | | |
+| | | | | | |
+| base | BitOps source | `bitovi/bitops:2.0.0-base` | - | `base` | `dev-base` |
+
+## Version Pinning
+* We always recommend pinning the stable version of BitOps to avoid any breaking changes like `bitovi/bitops:2.0.0`.
+* If the security is higher priority for you, use sha256 digest like `bitovi/bitops:sha256:82becede498899ec668628e7cb0ad87b6e1c371cb8a1e597d83a47fac21d6af3`.
